Abstract

The present invention is to solve the problem that a camera does not shoot a correct control area due to the deterioration of a camera rotation belt (timing belt) caused by the long-term use of a rotation camera used for controlling illegal parking and stopping, or the occurrence of a phenomenon in which the rotation zero point of the camera is deviated due to other reasons. When the deviation of the zero point of the rotation camera occurs, the deviation is inspected to accurately calculate the amount of displacement of the deviating zero point, and the coordinate values of a control target area are automatically collectively corrected by the amount of displacement, thereby accurately controlling illegally parked and stopped vehicles.

Description

Automatic Coordinates correction system of Vehicle control area}

In the present invention, when a phenomenon in which the rotational zero point of a rotational camera used in a vehicle enforcement system is deviating occurs, the amount of displacement from which the zero point is deviating is calculated, and the coordinates of the vehicle enforcement area are automatically corrected by the calculated amount of displacement to prevent illegal parking and stopping. It relates to an automatic correction system for vehicle control area coordinates that enables accurate and effective control of vehicles.

In the case of a system for automatically and unmanned enforcement of vehicles entering an illegal parking zone, a fixed camera or a rotating camera is used for vehicle detection or enforcement. Among these, in the case of a rotating camera, in particular, a rotational motion is often used for vehicle enforcement. If the camera is used for a long time, the timing belt used for the rotational motion may deteriorate and the accuracy of the operation may deteriorate. A situation in which the position of the camera is changed may occur due to a cause such as an external impact being applied to a post supporting the camera.

If the timing belt is worn out and loosened, even if the camera is rotated according to the position value set at the time of system installation, the camera cannot be accurately directed to the enforcement target area, and the image obtained through the camera does not properly capture the vehicle subject to enforcement. Instead, a problem may occur in which only a part of a surrounding object or vehicle is photographed.

On the other hand, even when the position of the camera is changed due to an external impact on the rotating camera itself or the surrounding elements supporting the camera, the camera is not accurately aligned toward the vehicle subject to enforcement, and the image has an error corresponding to the change. will create

The above zero point deviation phenomenon that occurs in rotating cameras is the biggest cause of aging of the belt installed in the camera. In particular, the rotational camera used in the illegal parking enforcement system not only uses the rotation function more frequently than cameras for other purposes such as security systems, but also operates at a high rotational speed for rapid enforcement, so the belt is inevitably deteriorating faster. .

In the case of the conventional vehicle enforcement system, in most cases, there is no countermeasure against the zero point departure phenomenon of the rotating camera, and even when a technology for compensating for the error of the camera is presented, its function is limited.

Among the prior art, a technique using a method of calculating the amount of displacement by attaching a certain mark to the inside of the transparent dome cover has been proposed only for cameras using a hemispherical transparent dome (Korean Patent No. 10-1704427, 2017.02.02 . registration), it is difficult to use this technology because the recently used outdoor rotary camera does not use a transparent dome cover.

In addition, a method of detecting and comparing feature points in real-time images was devised, but in the case of this technology, it was difficult to extract accurate feature points because it was sensitive to changes in landscape over time, changes in illumination during the day and night, and weather changes. Patent No. 10-1817509, 2018.01.05. Registration).

In addition, in the apparatus for acquiring object information for improving object recognition efficiency by correcting an object recognition error due to a positional displacement between cameras, a pre-stored first control value corresponding to the position coordinates of a predetermined object in an image of a first camera is a control unit for controlling a second camera based on the basis and estimating a second control value by controlling the second camera so that the object is located in a reference area within an image of the second camera; and the first control value and the second control value. There is also a prior art related to an object information acquisition device that calculates an error value between values and corrects the first control value based on the error value (Korean Patent No. 10-1822429, registered on January 22, 2018).

As described above, in the conventional vehicle control system, there is no countermeasure against the change of the zero point that occurs when the zero point deviation of the camera occurs or when the camera is removed and reattached for reasons such as repair or inspection.

In the case of a zero point departure phenomenon in a rotating camera, the camera cannot properly control the set area, significantly reducing the enforcement rate, and cracking down on vehicles located in areas excluded from enforcement, such as inside a parking lot, resulting in civil complaints. It could be. Also, in order to recover the deviating zero point of rotation, the manager has to directly reset the zero points of the cameras in all enforcement areas, which may cause inconvenience.

Domestic Patent No. 10-1704427 (registered on February 2, 2017) Domestic Patent No. 10-1817509 (registered on 2018.01.05) Domestic Patent No. 10-1822429 (registered on January 22, 2018)

In the present invention, as the rotating camera used for illegal parking enforcement is used for a long period of time, the rotational belt (timing belt) of the camera deteriorates or the zero point of rotation of the camera is deviated due to other reasons, so that the camera can properly detect the enforcement area. In order to solve the problem of not being able to take pictures, if the rotational zero point of the rotating camera is deviating, the deviance state is inspected to accurately calculate the amount of displacement of the deviating zero point, and the coordinates of the control target area are calculated by the amount of displacement. It is to provide a system that can accurately perform crackdown on illegally parked vehicles by collectively correcting the values.

In addition, it is to prevent civil complaints from occurring by enforcing vehicles parked and stopped at points other than the enforcement area by allowing the rotational camera to accurately photograph the enforcement target area.

The 'vehicle enforcement area coordinate automatic correction system' of the present invention relates to a technology that can be applied to a system that uses a single rotating camera to enforce parking violation vehicles, and the timing belt is stretched by using a vehicle enforcement camera for a long period of time. If the zero point of the rotatable camera deviates from the initially set value for any reason, such as detecting the deviating situation and accurately calculating the amount of displacement of the deviating zero point, the coordinates of the vehicle enforcement area are automatically and collectively determined by the calculated amount of displacement. It is about the technology to correct it.

The system of the present invention is configured to operate automatically, and every time the set zero-point inspection time elapses, the system automatically checks whether the rotating camera is deviating from the zero point, calculates the amount of displacement according to the deviation from the zero point, and calculates the amount of zero point displacement caused by the deviation If it is determined that this tolerance range (displacement amount standard) is exceeded, an operation of collectively correcting the intermittent region coordinates by the amount of displacement is performed.

The overall configuration of the present invention is as shown in FIG.

'Vehicle Enforcement Area Coordinates Automatic Correction System' of the present invention includes a field unit 100 installed at a enforcement site, a situation room unit 300 installed at a remote location from the field unit, and the field unit and the situation room through wired and wireless communication means. It is configured to include a wired/wireless network 200 for connection.

The site unit 100 of the present invention includes an imaging unit 110 installed at a enforcement site and photographing a vehicle, a zero mark unit 120 attached to a means such as a pole or a control box, and a wired or wireless network. It is configured to include a communication unit 130 that performs communication with the situation room unit. Field unit 100 may be formed in the form shown in the figure shown in FIG.

The imaging unit 110 is composed of a rotating camera 111 such as a CCTV camera as a means for obtaining an image of a vehicle subject to enforcement. The rotary camera 111 used in the present invention is a camera that takes pictures of the enforcement area through PTZ control, and the present invention is configured to operate the system using a general-purpose rotary camera product, not a specific product there is.

The zero mark unit 120 provided in the field unit 100 is used to detect the range of zero point deviation, that is, the amount of zero point displacement, and is configured to include a zero point detection mark 121 and a zero reference mark 122.

As in one embodiment of FIG. 2 , the field unit 100 may be configured such that a zero point detection mark is attached to a side surface of an enclosure installed on a support supporting a camera.

4 shows an embodiment of the zero point detection mark 121 and the zero reference mark 122 used in the present invention, and the zero point reference mark 122 is provided at the center of the zero point detection mark 121. As shown in FIG. 4, the zero point reference mark 122 is preferably provided at the center of the zero point detection mark 121, and the camera can focus on the center point, that is, the camera can easily focus on the center point. It is preferable to be made in a form that can be done. The PTZ value of the zero-point reference mark 122 acquired by the camera during the zero-point inspection is the position value of the camera in a state in which the camera is aligned toward the zero-point reference mark. 'Alignment of cameras' used in the description of the contents of the present invention means that the camera operates to focus on a photographing target while performing zoom-in and rotation operations.

The situation room unit 300 of the present invention configured as shown in FIG. 1 is installed in a situation room located remotely from the field unit 100, and the system automatically adjusts the zero point of the rotatable camera through the operation of the management server 310. And it is configured to perform an operation of correcting the intermittent area coordinates. The situation room unit 300 of the present invention is a control signal between the management server 310 that controls the overall operation of the system for zero-point correction of the rotatable camera and the situation room unit 300 and the field unit 100 through a wired or wireless network. It is configured to include a communication unit 330 that performs communication functions such as transmission and reception of images and transmission of image data.

The management server 310 provided in the situation room unit 300 includes a detection model building unit 311, a zero reference coordinate setting unit 312, an enforcement area setting unit 313, a control unit 314, and a remote camera. It is configured to include a control unit 315, a zero mark detection unit 316 and an intermittent area correction unit 317.

The detection model building unit 311 is for the system of the present invention to accurately recognize the zero-point detection mark and zero-point reference mark, which are the criteria for zero-point adjustment, and use them for zero-point adjustment of the camera. After the system of the present invention learns the shape of the zero-point detection mark and zero-point reference mark to be recognized through deep learning using images such as numerous photographs, the zero-point detection mark and zero-point reference recognized as a result of the learning It is a means to store the shape of the mark.

In order to accurately recognize the zero-point detection mark and zero-point reference mark, numerous photos or videos containing these zero-point marks are used. By learning the labeled zero-point detection mark and the image of the zero-point reference mark through the learning process, if the same or similar image as the zero-point detection mark or zero-point reference mark is included among the photos or videos taken by the camera during subsequent system operation, The system of the present invention recognizes the image as a zero-point detection mark or zero-point reference mark, directs the camera toward the zero-point detection mark or zero-point reference mark, and then controls the camera to align toward the zero-point reference mark.

The zero-point reference coordinate setting unit 312 is for setting and storing zero-point reference coordinates that become reference position values of the zero-point of the camera used in the zero-point inspection of the rotatable camera. The zero reference coordinates are set when the system is initially set, or when restarting the zero point inspection operation after checking the system. The value of the zero reference coordinate is the PTZ value corresponding to the position value of the zero reference mark attached to the fixture around the camera.

In setting the zero reference coordinates, the manager remotely controls the camera in the situation room 300, detects the zero reference mark provided in the field unit 100, obtains the coordinate value of the zero reference mark, and then obtains the coordinate value. It is made by a method of storing in the zero reference coordinate setting unit 312.

The zero reference coordinates set and stored in the zero reference coordinate setting unit 312 of the present invention are reference values for comparison with the detection zero coordinates, which are the location values of the camera zero points detected during the zero point inspection operation of the camera.

The 'zero point displacement' used in the present invention means the coordinate value difference between the zero reference coordinates and the detection zero point coordinates, and the 'displacement amount standard' is the allowable value of deviation from the rotation zero point set in the system of the present invention. In the present invention, when the calculated zero-point displacement is within the displacement standard, it is determined that the zero-point of the camera is not deviated.

When it is determined that the zero-point displacement of the camera exceeds the displacement standard, the system of the present invention corrects the coordinates of the enforcement area of the vehicle as much as the detected zero-point displacement, and the correction of the enforcement area coordinates is performed by It is done through the government (317).

On the other hand, the value of the zero point reference coordinate set in the above manner remains the same without changing while the system of the present invention normally operates. However, when the system is reset or the enforcement area of the vehicle enforcement system to which the present invention is applied is changed, the zero point reference coordinates may be reset.

If the zero-point displacement exceeds the displacement standard set in the system during the zero-point inspection, the system of the present invention collectively corrects the coordinates of the enforcement area corresponding to the value so that the camera can control the vehicle targeting the correct enforcement area. let it be

Enforcement area setting unit 313 is a means for setting the coordinate values of the vehicle enforcement area, which is the range in which vehicles illegally parked and stopped through the system of the present invention, that is, the range subject to enforcement. Setting the coordinates of the enforcement area is a process that is performed after the zero point reference coordinates are input and saved, and inputs the coordinate values of the camera for each part (point) of the enforcement area to the system. 313) is done.

In order to set the enforcement area during system setting, the manager of the situation room directly controls the camera remotely while the zero point reference coordinates for the rotating camera are stored, determines the coordinates of each part of the enforcement area, and inputs them to the enforcement area setting unit 313. , will be stored. The coordinates of the enforcement area set in this way become a reference value for the position of the enforcement area used without being changed during the operation of the system.

In the vehicle enforcement process to be performed thereafter, enforcement of illegally parked and stopped vehicles is performed using the enforcement area coordinates and the zero-point displacement stored in the enforcement area setting unit 313 .

The controller 314 is a means for controlling the operation of various components included in the management server 310 . That is, the control unit detects the current zero point value of the rotating camera by operating each component provided in the management server 310 of the present invention according to the order shown in FIG. It is a means of controlling the overall operation of the system to be calibrated correctly.

The control unit 314 controls information such as image data, zero reference coordinate data, control area coordinate data, etc. of the zero point detection mark and zero point reference mark detection model stored or set in the components of the management server, and a photograph taken by a camera and provided. The current zero point value (detection zero point coordinates) of the camera is calculated using the image data of the etc., and the overall operation of the system of the present invention, which collectively corrects the coordinates of the vehicle enforcement area, is controlled using the calculated result.

The control unit 314 of the present invention may be composed of a separate means such as an MCU, or may be composed of a program that performs the above functions while being included in each related component rather than a separate means.

The camera remote control unit 315 is a means for controlling the operation of the rotary camera installed in the site. The rotatable camera may be operated by a manager manually manipulating the camera remote control unit 315 or may be operated automatically according to a program built in the camera remote control unit 315 and instructions from the control unit.

This system is set based on the automatic operation of the rotational camera, and manual operation is required during the initial setup to start the system after system setting or when the manager has to manually reset the system due to a problem with the system. It is configured so that it can also operate as That is, the vehicle enforcement system to which the present invention is applied is automatically operated through the control of the camera remote control unit 315 and the control unit 314 after all items necessary for the operation are set, and the vehicle enforcement and enforcement area coordinates are corrected. will perform

The rotational camera used for vehicle enforcement is intended to capture and enforce images of vehicles illegally parked and stopped within the enforcement area. It is also used for detecting the degree of deviation (amount of zero point displacement).

The camera remote control unit 315 is also used to set the coordinates of the enforcement area. That is, in the present invention, after the system is installed, in order to set the range of the enforcement target area, the administrator acquires the position value of each control target area using the camera remote control unit in the situation room, and the obtained coordinates (position values) of each control area. is stored in the intermittent area setting unit 313. The setting of the coordinates of the enforcement area is performed through the camera remote control unit 315 and the control unit 314.

The camera remote control unit 315 is also used for an operation of detecting and recognizing a zero point detection mark and a zero point reference mark in order to correct the deviating zero point of the rotatable camera according to the present invention. In the present invention, after the control unit 314 determines whether or not the set zero inspection time has elapsed, if the inspection time has elapsed, the rotary camera is operated through the camera remote control unit 315 to operate the zero point provided in the field unit. An image of the part including the detection mark and the zero reference mark is photographed, and the photographed image is transmitted to the zero mark detection unit 316 .

The zero mark detection unit 316 receiving the image above detects a zero detection mark or a zero reference mark among the received images, and then obtains a detection zero coordinate, which is a positional value of the zero reference mark at that point in time. As a result of comparing the detection zero coordinates obtained as above with the zero reference coordinates previously stored in the system, if the current zero value (detection zero coordinates) of the camera exceeds the displacement standard and deviates (the zero point displacement exceeds the displacement standard) case), the coordinates of the intermittent region are collectively corrected by the amount of displacement through the intermittent region correction unit 314. For reference, 'detection' or 'acquisition' used in relation to the 'detection zero point coordinates' of the present invention are names that can be understood in the same meaning.

The system of the present invention is configured in principle that the rotational camera is automatically operated, and is manually operated only when the system is initially set or when an administrator directly resets the system after inspection due to an error in the system. Consists of.

After all the items necessary for the operation of the system are set, the rotatable camera of the present invention is automatically operated through the control of the camera remote control unit 315 and the control unit 314 to perform vehicle control and also, the set zero-point inspection time elapses Detects the position value (detection zero point coordinates) of the rotation zero point of the camera by transmitting the photograph including the zero point detection mark and the zero point reference mark, and transmitting the photographed picture to the zero point detection mark unit 316. let it do

The zero mark detector 316 is a means for detecting a zero point detection mark and a zero reference mark in order to check the zero state of the rotatable camera. In the system of the present invention, the zero mark detection unit 316 is for operating the rotatable camera to detect a zero point detection mark or a zero reference mark, and to detect the current zero point value of the camera using the mark. The system of the present invention detects a zero mark (zero point detection mark and/or zero reference mark) through the zero mark detection unit 316 when the set zero inspection time is reached while performing vehicle control, and the current position of the detected zero reference mark. The detection zero point coordinate, which is a value, and the zero point reference coordinate set in the system are compared to calculate the deviation value of the camera zero point, that is, the zero point displacement amount. After determining whether or not the calculated zero point displacement amount is within the normal range, the displacement amount is within the allowable range standard), the coordinates of the vehicle control area are collectively corrected by the amount of displacement.

The zero mark detection unit 316 of the present invention is configured to automatically perform the above operation whenever the zero check time set in the system elapses. The zero point inspection time can be set, for example, in units of 3 hours or 1 day. In this case, the current zero point value of the camera is detected at a set time every 3 hours or once a day, and the coordinates of the enforcement area can be corrected. there is.

The zero point detection mark and the zero point reference mark used in the present invention may be formed in the form of the example shown in FIG. 4 . The zero-point reference mark is mainly located at the center of the zero-point detection mark, and the zero-point detection mark and zero-point reference mark can be attached to a camera installation support or system control enclosure close to the camera, or can be attached to other fixtures such as buildings around the camera. there is.

The zero-point detection mark and zero-point reference mark are attached and installed at a position that the system can predict, but it is preferable to attach them at a position where the rotary camera can easily rotate toward the mark and recognize the zero-point detection mark and zero-point reference mark. In the present invention, the name zero mark is used to collectively refer to the zero point detection mark and the zero reference mark.

When it is time to check the zero point during the operation of the system of the present invention, the rotary camera rotates toward the position where the zero point detection mark or zero point reference mark is predicted to be attached to take a picture, and the image included in the photograph is captured. Among them, zero detection marks and zero reference marks are recognized and detected. Since the system of the present invention has already learned the images of the zero detection mark and the zero reference mark through deep learning before the setting, when the zero detection mark or zero reference mark is included in the image of the photographed photograph, it quickly recognizes these marks. can do. When the zero point detection mark is recognized, the zero reference mark included therein can also be easily detected.

When the system of the present invention determines that a zero point detection mark or a zero reference mark is included in a photo or video image taken by a camera, the recognized zero point detection mark is zoomed in to find the zero reference mark, and then the camera is focused. In the state of aligning with the center point of the zero reference mark, the detection zero point coordinate, which is the current position value of the camera zero point, is obtained.

The control unit 314 that has obtained the detection zero point coordinates compares the zero point reference coordinates previously stored in the zero point reference coordinate setting unit 312 with the detection zero point coordinates to calculate the degree of camera zero point deviation, that is, the zero point displacement of the camera.

The intermittent region correcting unit 317 is for collectively correcting the coordinates of each intermittent region when the calculated zero-point displacement exceeds the displacement standard. That is, when it is determined that the zero point displacement calculated through the zero mark detection unit 316 exceeds the displacement amount standard (allowable range), the control unit 314 controls the regulation area setting unit 313 through the regulation area correction unit 317. The coordinates of the intermittent region previously stored in the intermittent region are corrected by the calculated amount of zero point displacement to reset the coordinates of the intermittent region.

If the zero-point displacement of the camera exceeds the displacement standard, the rotational camera is in a difficult state to effectively enforce vehicle control, and thus it is necessary to reset the coordinates of the enforcement area. In the present invention, the preset coordinates of each intermittent region are collectively corrected according to the amount of zero point displacement calculated as above.

On the other hand, if the zero point of the camera deviates beyond the allowable range, as shown in FIG. If in , etc. The intermittence area correction unit 317 of the present invention compares the zero reference coordinates previously set through the zero reference coordinate setting unit 312 with the detection zero coordinates obtained during the zero inspection, and sets the intermittence area coordinates as much as the amount of zero displacement calculated. It is corrected, and when corrected in this way, the rotational camera can again take an image of an accurate enforcement area.

The system of the present invention detects the zero point of the camera and corrects the coordinates of the enforcement area through the steps shown in FIG. 3 . Details of the operation performed in the present invention are as follows.

- Establishing a detection model for the zero point detection mark and the zero reference mark (PS)

In the present invention, prior to the system performing an operation, after learning the image of the zero detection mark and the zero reference mark by using deep learning technology, the system can easily use the zero detection mark and the zero reference mark based on the learned recognition. The detection model construction step, which is a preliminary step (PS) to prepare for recognition, is performed first. The pre-step (PS) is performed in advance before the system of the present invention starts operating, and this step is not shown in FIG.

In the present invention, in order for the zero mark detection unit 316 to accurately recognize the zero point detection mark and the zero reference mark, the zero point detection mark and the zero reference mark are obtained by photographing them at various focusing distances, angles, and illuminances before setting the system. After learning numerous images by deep learning method, the zero detection mark or zero reference mark included in the images taken by the camera can be accurately recognized during subsequent system operation.

In this system, the process of building the detection model of the zero detection mark and the zero reference mark with the above contents is performed through the detection model building unit 311, and the detection model building unit 311 uses the deep learning Images such as numerous photos or videos are stored.

As described above, the step of constructing the detection model for the zero point detection mark and the zero point reference mark is performed in advance before the system of the present invention starts vehicle enforcement and camera zero point correction operations.

- Zero reference coordinate setting step (S10)

In the setting process for operating the system of the present invention, the step of setting the zero reference coordinates through the zero reference coordinate setting unit 312 (S10) must be performed.

The zero reference coordinates are set by the manager remotely controlling the rotary camera from the situation room to align the camera to the center of the zero reference mark, and then detecting the position value (PAN/TILT/ZOOM) to set the zero reference coordinates ( 312). In the present invention, the zero point reference coordinate is for comparison with the detection zero point coordinate, which is the current zero point value of the camera detected during the operation of the system thereafter, and corresponds to very important data in the operation of the system of the present invention.

In order to set the zero reference coordinates, first, the camera must be moved so that the zero reference mark is visible on the display provided in the situation room so that the zero reference mark appears in the image of the screen captured by the camera. At this time, the direction of the camera does not need to be accurate, and it is sufficient to move the camera so that the mark is visible on the screen. Thereafter, the control unit 314 controls the zero mark detection unit 316 and the camera remote control unit 315 to automatically center the camera so that the zero reference mark is aligned at the center of the screen. The PTZ value of the camera detected in this aligned state becomes the zero point reference coordinate of this system.

In addition, when the zero reference coordinate setting button provided in the zero reference coordinate setting unit 312 is pressed while the zero mark is visible on the screen, the camera automatically zooms in and performs center alignment to align the zero reference mark to the center of the screen. may make it so. The PTZ value of the camera detected in this aligned state also becomes the zero point reference coordinate of the present system.

- Vehicle enforcement area reference coordinate setting step (S20)

Another one of the steps performed in the preparation process for operating the system of the present invention is the step of setting reference coordinates for the control target region (S20). This step is performed after the step of setting the zero point reference coordinates, and may be referred to as the step of setting the vehicle control area or the step of setting the control area reference coordinates.

The control area reference coordinates used in the present invention are position values given according to the location of the enforcement area during system setting, and are reference values used when correcting the enforcement area according to the zero point inspection result.

The setting of the control area reference coordinates is performed when setting the system or resetting the system after checking the system, and is performed through the control area setting unit 313. The control area reference coordinates are the position values set by the administrator while controlling the camera remotely from the control room. It is set in a way, and the set regulation area reference coordinates are stored in the regulation area setting unit 313. If there are multiple enforcement areas, this operation is repeatedly performed for each enforcement area to set and store the control area reference coordinates for all enforcement areas.

As a result of the system of the present invention performing the zero-point inspection, when it is determined that the rotation zero point of the camera exceeds the displacement standard and deviates, the enforcement area correction unit 317 corrects the coordinates of the entire enforcement area collectively, The correction of the coordinates of the enforcement area at this time is to correct the coordinate value of the enforcement area by the detected zero-point displacement based on the reference coordinates of the enforcement area. That is, when the zero point of the camera is reversely corrected by the amount of zero point displacement from the reference coordinates of the enforcement area, the coordinates of the enforcement area are correctly corrected.

When the control area reference coordinates are set through this step (S20), the system of the present invention is in a state in which vehicle control and control area coordinate correction operations can be performed.

- Inspection of deviation from rotation zero point and correction of intermittent area coordinates (S110, S120, S130, S140, S150, S160)

When preparations are made for the operation of the system through the previous steps (preliminary steps, S10 and S20), the system of the present invention can perform a vehicle enforcement operation (S100), and at the same time set the zero point of the camera. You can also perform an inspection operation.

Vehicle enforcement using a rotating camera is performed continuously or at a fixed time period, and the operation for zero point correction of the camera is performed according to the zero point inspection time interval set in the system. That is, the zero point inspection of the camera is performed every time the zero point inspection time set in the system elapses.

As in the case of the present invention, when the rotation type camera is used for a long period of time in a system for performing vehicle enforcement using a rotation type camera, the zero point of the camera may deviate. As a result, as shown in FIG. 7 (b) , a problem arises in that the camera captures an area that partially or entirely deviated from the enforcement area. This phenomenon may be caused by the aging of the timing belt used in the rotary camera, or may be caused by a change in the position of the camera due to an external force acting on a post supporting the camera.

The present invention is to improve the inaccuracy problem of vehicle enforcement that can occur when the rotation zero point of the camera deviates due to the above circumstances. If the zero point is deviated beyond the allowable range set in the system, calculating the deviation range (zero point displacement) and collectively correcting the coordinates of the control area by the calculated deviation range, that is, the zero point displacement (S120, S130, S140, S150, S160) are performed. The present invention can set the system to check the zero point of the camera, for example, every 3 hours or once a day. In addition, the time interval may be set differently according to the environment or condition of the field unit or the manager's choice.

During the zero point inspection of the camera, in the present invention, the camera is rotated to move to the position of the zero point mark through the control unit 314 and the camera remote control unit 315, and when the zero point mark is detected, the center of the zero reference mark 122 While controlling the camera to align toward the camera, the PTZ value of the rotation type camera at the aligned position, that is, the detection zero point coordinate (zero point position value of the camera at the time of detection) is obtained through the zero mark detection unit 316 (S120). , S130).

After acquiring the detection zero coordinates as above, the control unit 314 compares the zero reference coordinates previously stored in the zero reference coordinate setting unit 312 with the obtained detection zero coordinates, and compares the zero point deviation range, that is, the amount of zero point displacement. is calculated (S140).

If the calculated zero-point displacement is below a certain value, that is, within the displacement standard, the control unit 314 determines that the rotation zero point is normal, stops the correction-related operation, and continues the operation for vehicle control ('no in S150). 'In the case of).

Conversely, when it is determined that the calculated zero-point displacement exceeds the displacement standard, it is determined that the rotational zero-point of the camera is deviated, and an operation for correcting the coordinates of the enforcement area is performed.

The deviation range of the zero point calculated above, that is, the zero point displacement is the primary result to be obtained in the present invention. will be corrected by In this way, the coordinates of the intermittent area corrected collectively by the amount of zero point displacement are referred to as 'corrected intermittent area coordinates'. Thereafter, the system of the present invention performs a vehicle enforcement operation using the corrected enforcement area coordinates, and as a result, vehicle enforcement can be performed targeting an accurate area.

In the present invention, the P value (panning value; Pand) and the T value (tilting value; Tiltd) among the zero point displacements of the rotatable camera can be obtained in the following manner.

As described above, whether or not the rotation zero point deviation of the camera made in the system of the present invention is inspected, and if it is determined that the camera is deviated, the amount of zero point displacement caused by the deviation is calculated, and then the coordinates of the enforcement area are calculated by the amount of zero point displacement. It is corrected, and the operation of the present invention made as such is performed as follows while sequentially passing through steps S110, S120, S130, S140, S150 and S160 shown in FIG.

The contents of each step in which the system of the present invention inspects the zero point of the rotatable camera and corrects the coordinates of the enforcement area are performed in the order shown in the following contents and FIG. 3.

First, if it is determined that the zero point inspection time set in the system has elapsed during the vehicle enforcement process (S110), the control unit 314 uses the camera remote control unit 315 to display the zero mark (zero point detection mark) attached to the periphery of the camera. and the zero reference mark), the camera is rotated and moved (S120).

When the zero point detection mark is detected in the image captured by the camera while the camera is moving as described above, the control unit 314 recognizes the zero point detection mark through the zero mark detection unit 316, and again the zero point located at the center of the zero point detection mark. After detecting the reference mark, the camera is aligned toward the zero-point reference mark (S130). The position value (PTZ value) of the cameras aligned in this way becomes the current zero point value of the camera, that is, the detection zero point coordinates.

Having obtained the detection zero coordinates of the camera, the control unit 314 compares the zero reference coordinates previously set in the zero reference coordinate setting unit 312 with the detection zero coordinates obtained as above, and calculates the difference value, the zero displacement amount. It becomes (S140).

After calculating the zero-point displacement of the camera, it is determined whether the calculated zero-point displacement exceeds the 'displacement standard', which is an error tolerance value of the rotation zero point set in the system (S150).

If the calculated zero point displacement does not exceed the displacement standard, the control unit 314 determines that the zero point of the camera is in a normal state and stops the zero point inspection, and the system continues to perform the vehicle control operation (S100).

However, if it is determined that the calculated zero point displacement exceeds the displacement standard, the control unit 314 controls the regulation area correction unit 317 to collectively correct the coordinates of the vehicle regulation area by the value corresponding to the calculated zero point displacement. It is done (S160).

The step of inspecting whether or not the rotational zero point deviate from the rotational zero point and correcting the intermittent region, as described above, is a step performed when the zero mark detection unit 316 can immediately detect the zero mark (zero point detection mark and/or zero reference mark) ( for S130 'yes'). That is, when the zero mark detection unit 316 can directly detect the zero point detection mark and/or the zero reference mark from an image such as a photograph taken through a rotary camera, steps S110, S120, S130, S140, S150 and S160 Each step is performed in order.

On the other hand, if the zero mark detection unit 316 cannot detect the zero mark (zero point detection mark and/or zero reference mark) (in the case of 'no' in S130), steps described below are additionally performed. .

- Additional steps performed when zero mark detection fails (S131, S132, S133, S134, S135, S136, S137)

The zero point detection mark and the zero point reference mark used in the present invention may be formed in a form as illustrated in (a) or (b) of FIG. The area of the zero point detection mark is relatively wide compared to that of the zero point reference mark, so the camera can easily recognize it. The zero-point detection mark and the zero-point reference mark may be of any form other than FIG. 4 as long as they are easily detectable by the zero-point mark detection unit 316 .

On the other hand, Figures 5 (a) and (b) shows an embodiment in which the zero mark (including the zero detection mark and the zero reference mark) is attached to one side of the enclosure fixed to the side of the support (pole).

In the system of the present invention, unlike Fig. 4 (a) and (b), it is also possible to use a zero point reference mark formed on one side of the zero point detection mark instead of the center. When the zero detection mark or zero reference mark used in the present invention is changed, the detection model building step described above should be performed again to train the system to recognize the new zero mark.

Even if the camera is moved to the position of the zero mark for zero inspection, the zero mark, that is, the zero detection mark or the zero reference mark may not be detected in an image such as a photograph taken by the camera. When the zero mark is not detected, when the camera's zero point changes excessively and cannot find the position where the zero mark is attached, or when the camera is in a normal state but the zero mark is damaged or dropped. If not found, etc.

In the system of the present invention, the control unit 314 controls the zero mark detection unit 316 and the camera remote control unit 315 to perform the following operations to detect the zero mark. Alternatively, if the detection of the zero reference mark fails (in the case of 'no' in S130), the following steps are performed to detect the zero mark.

First, in the present invention, an operation of zooming out a rotatable camera and detecting a zero mark is performed (S131 and S132). Steps S131 and S132 performed at this time are steps for detecting the zero mark only with a zoom-out operation without rotating the camera. Since the zero mark is attached to a position set so that the system can predict it, the zero mark can be detected through zooming out of the expected position, as shown in FIG. 6 (a). If the zero mark is not detected even after one zoom-out, zoom-out is performed again, and at this time, as in the case of FIG. 6(b), the camera is zoomed out to the maximum to detect the zero mark.

When a zero point mark is detected in a picture taken during a zoom-out operation (in the case of 'yes' in S132), the controller 314 aligns the camera toward the center of the zero point reference coordinate included in the picture, and at the aligned position. The detection zero point coordinate, which is the current value of the camera zero coordinate of , is obtained. After obtaining the coordinates of the detection zero point, the steps to correct the coordinates of the control area are performed, which are the same as those performed in the previous ‘rotational zero point deviation inspection and enforcement area correction step’.

Next, if the zero mark is not detected despite zooming out twice as described above (in the case of 'no' in S132), the controller 314 rotates the rotary camera at an angle less than the angle of view to detect the zero mark. The operation of is additionally performed (S133, S134, S135).

The angle of view of a camera refers to the range of horizontal and vertical angles captured on the screen of the camera, and the larger the angle of view of the camera, the wider range of shooting is possible. Therefore, if the camera is rotated and rotated below the angle of view of the camera, parts of the pictures (screen) before and after rotation overlap each other, so that no blind spots occur between the pictures taken. In the present invention, the zero mark can be effectively detected by allowing the camera to take pictures while rotating at an angle less than the angle of view.

On the other hand, in the present invention, rotating the camera below the angle of view means rotating (panning, tilting) the camera left and right and up and down so that a part that could not be captured only by the zoom-out operation can be captured and a zero mark can be detected. That is, the system of the present invention rotates (tilting) the camera up and down, and then performs a rotation operation of rotating (panning) the camera left and right at a predetermined angle.

The tilting operation of rotating the camera below the angle of view can be divided into downward tilting and upward tilting. After tilting downward or upward, a panning operation of rotating the camera left and right is performed. Whether to perform downward tilting or upward tilting first can be selected by the manager according to the site situation and set in the system, and can also be set by changing the range and order of rotation angles. In addition, the number of times of performing the rotation operation as described above can also be set.

For example, if the system is set to perform a panning operation after first tilting downward, the camera is rotated downward (tilting downward) by a set angle, and then the camera is rotated left and right (panning) by a certain angle to move the camera around the camera. will take a picture The panning operation may be performed at a predetermined angle. For example, if the panning angle is set to 60 degrees, the camera can take pictures of the entire surroundings while rotating 360 degrees by performing panning motions six times. The system of the present invention performs a zero mark detection step of checking whether or not there is a zero mark in a photograph taken during a panning operation (S134). When a zero point mark is detected in a photo taken during the panning operation (in the case of 'yes' in S134), the controller 314 aligns the camera toward the center of the zero reference coordinate included in the picture, and at the aligned position. The camera position value (PTZ value) of , that is, the detection zero point coordinate, which is the current value of the camera zero point coordinate, is acquired. After acquiring the coordinates of the detection zero point, the steps to correct the coordinates of the enforcement area are performed in the same way as in the previous 'rotational zero point deviation inspection and enforcement area correction step'.

If the zero mark is not detected even after performing downward tilting and 360-degree panning around the camera, the system tilts the camera upward again and then rotates (panning) the camera left and right by the set angle to detect the zero mark. will do it again After the upward tilting, the zero mark detection operation performed during the panning operation is the same as that of the downward tilting.

On the other hand, if the zero mark is not detected (in the case of S134 'no'), that is, in FIG. 3, S131- If the zero mark is not detected even though all steps of S132-S133-S134 are performed, the control unit 314 determines that an error has occurred in the zero mark and stops the operation for zero check (S134 and S135). Step S135 is a step of determining whether or not the number of tilting and panning operations performed during the zero point test exceeds the number set in the system. is stopped (S136).

When the zero mark is not detected, that is, when the detection of the zero mark fails, the system of the present invention stops the operation related to the zero check (S136), and displays the status on the display device installed in the control room 300. so that the manager recognizes that the zero point correction operation has been stopped (S137). Recognizing this situation, the manager takes appropriate measures, such as checking the condition of the camera and zero mark in the field.

On the other hand, the system of the present invention is configured to continuously perform vehicle control even when the operation related to the zero check is stopped (S100). Since vehicle enforcement needs to continue to be performed regardless of whether or not the zero point test is performed, the system of the present invention is configured to continuously perform the vehicle enforcement operation unless an abnormality occurs in the vehicle enforcement function itself. For example, since the zero mark may not be detected due to damage or falling, the system of the present invention is configured so that the vehicle control-related operation of the system is normally performed even if the zero-point inspection-related operation is stopped. .

After the zero reference mark is detected by additionally performing the above steps (S131, S132, S133, S134), the zero point displacement is calculated and calculated among the steps performed in the previous 'rotational zero point deviation inspection and intermittent area correction step' The same steps (S140, S150, S160) as for collectively correcting the intermittent region coordinates are performed according to the determined zero-point displacement amount.

As described above, in the present invention, the system automatically performs an operation of aligning the camera toward the zero reference mark. In addition, a zero reference coordinate detection button may be provided in the zero mark detection unit 316, and a manager may press this button to align the camera toward the zero reference mark. In this case, when the button is pressed, the camera automatically zooms in and performs center alignment, so that the zero reference mark is aligned at the center of the screen.

The PTZ value of the camera detected when the camera is aligned automatically or by pressing the button as above becomes the current zero point value of the camera, that is, the detection zero point coordinate.

In the present invention, when the zero-point displacement of the camera is calculated by directly detecting the zero-point reference mark, and when the zero-point reference mark is detected and the zero-point displacement of the camera is calculated by performing zooming out and rotating the camera within a set number of times, The system can perform normal zero point correction operation.

As a result of inspecting the zero point of the rotatable camera while performing the above steps, if the calculated zero point displacement exceeds the displacement standard, the controller 314 determines that the zero point of the camera is deviated, and the coordinates of the enforcement area by the calculated zero point displacement. is collectively corrected (S160), and this operation is performed through the intermittent area correction unit 317.

The types of position values or coordinates acquired or detected while the system of the present invention performs the zero check through the above steps are as follows.

First, in the case of the zero reference coordinate, the zero reference coordinate, which is the zero coordinate of the camera for the zero reference mark initially set in the preparation process for the system setting, and the camera for the zero reference mark detected as a result of performing the zero inspection operation. There is a detection zero point coordinate, which is the zero point coordinate of .

Next, in the case of the enforcement area coordinates, there are enforcement area reference coordinates, which are the coordinates of the enforcement area initially set in the preparation process for the system setting, and correction, which is the coordinates of the enforcement area corrected by reflecting the zero-point inspection result of the camera. There is a control area coordinate.

In the system of the present invention, the above four coordinate data are used in the following manner in the process of performing the zero-point inspection of the camera and the correction of the coordinates of the enforcement area when the zero-point inspection time has elapsed.

In the present invention, the zero-point displacement amount is calculated by comparing the zero-point reference coordinates preset in the zero-point reference coordinate setting unit 312 with the detected zero-point coordinates obtained in the zero-point inspection process, and the intermittent area coordinates are changed according to the calculated zero-point displacement amount to the previous one. Either it is kept the same, or the intermittent area coordinates are collectively corrected by the amount of zero point displacement.

If the calculated zero-point displacement is within the displacement standard, the intermittent area coordinates are not corrected and the previous coordinate values are maintained.

If the calculated zero-point displacement exceeds the displacement standard, the zero point of the camera is out of the permissible range, so the value of the zero-point reference coordinate must be changed. In this case, the control area coordinates must be corrected by the zero-point displacement. Correction of the coordinates of the enforcement area is to restore the state to a normal state where the picture taken by the camera car is out of the proper enforcement range because the zero point of the camera is deviated by the amount of zero point displacement from the normal enforcement range, and the previously stored enforcement area reference coordinates It is to regulate vehicles using the coordinates of the enforcement area corrected by reflecting the amount of zero point displacement in reverse.

The control area reference coordinates are set during system setting, and the coordinate values are not changed unless circumstances such as the need to reset the system occur. On the other hand, the value of the corrected enforcement area coordinates, which are the coordinates of the enforcement area modified by reflecting the zero point test result, can change whenever the zero point displacement is changed. That is, if the detected zero-point displacement is the same position value as the zero-point displacement calculated at the previous zero-point inspection, the coordinates of the corrected enforcement zone do not change, and if the position value of the zero-point displacement varies, the coordinates of the corrected enforcement zone change.

Effects expected from the system of the present invention configured as described above are as follows.

In the case of applying the technology of the present invention, when the rotational zero point deviation of the rotational camera occurs, the zero point check can be performed automatically, so that the vehicle enforcement efficiency of the system using the rotational camera can be increased.

In the system of the present invention, when the rotational zero point of the camera is deviated, the system automatically detects the amount of displacement that has deviated and corrects the rotational zero point of the camera by the amount of displacement, so that the coordinates of the vehicle enforcement area are collectively corrected as a result. As a result, the administrator can omit the task of resetting the coordinates of the entire enforcement area one by one.

When the system of the present invention is applied to vehicle enforcement, the coordinates of the enforcement area can be maintained accurately at all times, so that civil complaints due to enforcement of vehicles in areas other than the enforcement area can be prevented.

In addition, unlike conventional technologies, the present invention can also be applied to a vehicle enforcement system using a general-purpose rotary camera rather than a camera having a specific form or function applied thereto.

In the present invention, the camera installed in the vehicle enforcement system manages the range of the enforcement area by itself and, when an error occurs in the enforcement area, corrects the error by itself, so that the vehicle enforcement can be effectively carried out even if the manager does not reside in the situation room. Therefore, it is possible to increase the operational efficiency of the vehicle control system and greatly reduce the cost associated with the system operation.

As described above, the content of the present invention has been described in detail, and the technical idea of the present invention is not limited to the content described above, but those of ordinary skill in the art to which the present invention belongs are the same as the technical idea of the present invention. It should be construed as including those that are similar or similar and can be applied without special technical changes, and also similar or equivalent to the technical spirit of the present invention described in the claims as belonging to the scope of the present invention.
